[MPlayer-dev-eng] mga_vid memory detection error

[Eric Lammerts]

Hi,
I've got a 16Mb Matrox G400 card that is misdetected as a 32Mb model. The
result is a green screen. With mga_ram_size=16, everything works fine.
(I'm using the current CVS).

Since "lspci -v" reports "16Mb", wouldn't it be a good idea to use the
subsystem vendor/device id for the memory detection?

Eric
